Product Code GBF056
ASMS GBF056 Cement Grade Blended Granulate is a coarse sand-like material with a porous, amorphous structure ranging from white to golden brown in colour.
APPLICATIONS
GBF056 is predominantly used for grinding for cement replacement. Blended granulate is dried and either inter-ground with Portland cement clinker or separately ground and blended with Portland cement at cement or concrete plants.
COMPOSITION AND MATERIALS
GBF056 is a glassy, granular material produced by granulating blast furnace slag.
Blast furnace slag is the non-metallic product consisting essentially of silicates and aluminosilicates of calcium and other bases developed in a molten condition simultaneously with iron in a blast furnace.
Molten slag is passed through high volume water sprays which break the slag stream into small droplets which are rapidly quenched, suppressing crystallisation and resulting in a material with a porous, amorphous structure.
